Afaik most traffic anywhere on the internet is mobile where that shouldn't be an issue, no? When I type "quebec", it suggests both Québec and Quebec. So I put it to you that a majority of people simply don't know that the "correct" spelling needs the accent (and might even be slightly confused why their English keyboard would suggest French) and thus actively select the version without the accent, rather than it being inconvenient to type diacritics. Your Honour, I rest my case.

(I wouldn't bother with the accent either, even on my fancy physical keyboard with all the little bits and bobs)
